NAME
lvmdump - create lvm2 information dumps for diagnostic purposes
SYNOPSIS
lvmdump [options] [-d directory]
DESCRIPTION
lvmdump is a tool to dump various information concerning LVM2. By default, it creates a tarball suitable for submission along with a problem report.
The content of the tarball is as follows: - dmsetup info - table of currently running processes - recent entries from /var/log/messages (containing system messages) - complete lvm configuration and cache - list of device nodes present under /dev - if enabled with -m, metadata dump will be also included - if enabled with -a, debug output of vgscan, pvscan and list of all available volume groups, physical volumes and logical volumes will be included - if enabled with -c, cluster status info
OPTIONS
|
-h — print help message
-a — advanced collection | |
| WARNING: if lvm is already hung, then this script may hang as well if -a is used | |
| -m — gather LVM metadata from the PVs | |
| This option generates a 1:1 dump of the metadata area from all PVs visible to the system, which can cause the dump to increase in size considerably. However, the metadata dump may represent a valuable diagnostic resource. | |
| -d directory — dump into a directory instead of tarball | |
| By default, lvmdump will produce a single compressed tarball containing all the information. Using this option, it can be instructed to only produce the raw dump tree, rooted in directory. | |
| -c — if clvmd is running, gather cluster data as well | |
